Insulation Resistance Tester

Identifying and correcting problems before they result in a failure occurs through regularly scheduled preventative maintenance.

Insulation resistance tester.

A megohmmeter also called insulation resistance tester teraohmmeter is then used to. The megger insulation tester is a small portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. Insulation resistance testing is used as a quality control measurement. Whether you work on motors generators cables or switch gear the fluke digital insulation resistance testers provide noise free reliable results.

With advanced performance the insulation tester line is designed to be safe simple to use and gimmick free. To help eliminate this lack of understanding let s discuss in detail insulation resistance ir testing and the megohmmeter. The insulation resistance test consists in measuring the insulation resistance of a device under test while phase and neutral are short circuited together. The measured resistance has to be higher than the indicated limit from the international standards.

The insulation resistance test is the second test required by the electrical safety testing standards. The megger insulation tester is essentially a high range resistance meter ohmmeter with a built in direct current generator. For good insulation the resistance usually reads in the megohm range. Megger have over 100 years of experience and leadership in providing high performance insulation testers for electrical equipment diagnostic applications.

Insulation resistance meters that can generate two or more rated measurement voltages since different insulation testers provide different combinations of rated measurement voltages it is necessary to choose an instrument that provides the combination of values that is best suited to the application at hand. Developed early in the 20th century the insulation resistance ir test is the oldest and most widely used test for assessing the quality of insulation.

Whether the dielectric is good or bad to evaluate a number of test results on the same piece of equipment you have to conduct the test the same way and under the. Insulation resistance testing should begin at the time of installation and continue throughout the lifetime of the equipment.
